3 Use the table to enter the values for the depth, the fill slope, the cut slope, the
base width, and the base grade.
The base width and grade are used to create benches with the stepped slope
type. The first depth should be zero (0). Benches are applied at the indicated
depth and slopes are applied from the depth they are associated with, to the
beginning of the next slope segment below. Depths are always presented in a
sorted order. When a new depth is added, the command automatically inserts it
in the proper place.
Use the following buttons to navigate and edit the table:

Use the navigation buttons to move through the lines and pages of slope
information. For a description of the navigation buttons, see Editing the
Existing Ground Cross Section Data in this chapter.
n
Click Insert to insert a new depth or enter the new depth in a blank field at
the end of the list.
n
Click Delete to remove a depth and all its associated information. A warning
dialog box is displayed before deleting the depth. Click Yes to delete the
selected depth.
n
Click Save to save changes without exiting the Depth Control Editor dialog
box.
4 Click OK to exit the dialog box, or Cancel to exit the command without making
changes.
NOTE
If you make changes in the Stepped Control Editor, then you must
reprocess the cross sections using the Process Sections command.
Changing the Surface Slope Settings
Surface slope condition is applicable only when the finished ground cross
section is in a cut condition and passes through different layers of soil type. For
economic design, each layer of soil may specify different side slopes. In this
approach, the slope used at various segments of side slope is determined by the
surface type through which the cut slope passes. This is useful for situations in
which the cut passes through a layer of rock. This ledge can either be set to
follow the surface or it can be set to bench at a specified grade.
